This invention relates tofimprovements in apparatus for insuring sanitation in thematter of delivery of drinking water or other liquid to be directly olu'affed.y s

f `The primary objects in View are accentuation of sanitation and facility of use in connection with an ordinaryfspigot.

More detailed objects will become apparent hereinafter and will in part be stated.

Vitli theseland otherobjects in -view,the invention includes a battle disposed ,inl the path of discharge from a font anda control actuatedv thereby for governing drainagel from the discharge. .Y l l The invention in greater. detailincludes a baille located in the path V,of discharge of a .drinking font and .a control valvetfor the drainage of the font connected to thebale for enabling the bafflejto close the valvefagainst Aand claimed.

.drainage during the regular flowfrom the font.

The invention. also comprisesl certain other novel constructions, combinations, and arrangements of parts as subsequently specified Inthe accompanying. drawings,- 1 F igurel is alongitudinal, vertical, central section of an apparatus embodying the fea-V tures of the presentinvention andshown ja-s applied to a spigot, the latter beingseenin elevation. v

Figure 2 .is a horizontal section taken on j the'planel indicated by line 2-2 of Figure 1, looking downward. 1 Figurer?) is a vertical section taken on plane indicated by line 3-3 of Figure 1, and looking in the direction indicated by the arrow. y I

Figure 4 is a View similar to Figure 1 of a somewhat modified embodiment, parts being broken away for the saving of space. l Referring to the drawings Vby numerals, 1 indicates the ordinary house spigot having the usualdischarge nozzle 2. A clamp 3 detachably engages the nozzle 2 in position for leaving the lower or extreme edge portion of the nozzle exposed beneath the clamp. `The cla-mp 3 is susceptible of quite a widel range of modication in the details of its construction, butpreferably includes a pairfof arms the y 4 fromL `Which outstands rearwardly a plate 5. MThe/arms tf-are internally, transversely grooved and containa gasket 6 which snugly surrounds the nozzle 2. The `gasket '6 isan appropriate'packing unit, and lmay be a ground metal ringer afsoft metal packing or of otherapproprate packing materiahsuch as rubbervor leather, and is .preferably crosscut at 6"'t4olfacilitateassemblage within the .arms 4t. The -gasketfis assembled inthe arms before4 the clamp Sisappliedfto lthefnozzle 2. The outer or forward ends-fof the arms l are 4formedinto.@outstanding parallel tabs 7, 7, perforated and engaged by a bolt 8 passing through said tabs'and designed toclraw the free end portions oftthe armsll Vtoward each other for iirmlyclamping the gasket 6 against the circular exterior surface of nozzle 2. Of course,` the.l arms Atare `permitted to spring apart by relaXing'or backing-off the nut of bolt 8 whentheclamp 3 isvnto be applied or y removed from the nozzle 2. 1

y A'fountain tube 9 is arranged with a rearward extension 10, disposed with its upper face parallel land` contiguous tothe under faceV ofthe plate 5. A bolt 11, 'or other appropriateanchorage, depends from the plate 5 and sustains the extension 10 and its connected parts. Boltfll preferably is headed, and has its head seated in an appropriate recess `in the upper face of plate 5, and depends through the .plate and through theextension 10 and is engaged by a clampnut 12 between which nut and* the extension 10 a coiled spring 13 is interposed, sothat `screwing up on the nut 12 will compress the spring 13 against the extension 10,v and thereby stress witha gasket 15 surrounding theinner teryminus of thebore of the'tube and locatedto contact with the exposed edge of the nozzle 2 under sufficient stress of the Vtension of spring 13 to effect a non-leaking joint between the nozzle 2 and the bore of the tube 9. Upstanding from the extension 10 preferably at diametrically*opposite sides of the bolt 11 are lugsl,16,'fdisposed to engage cam` faces 17, 17 in the under portion of plate 5, said Cain faces beingV proportioned and located to .cause the extension 10 to. move' downward' against the tension of' spring 13 whenever the tube'9 is swung horizontally about the boltrll as a pivot.l Thecamfaces 17 are preferably formed in recesses in the plate so as to be concealed,

and are so located that when the tube 9 is positioned to outstand directly from Vthe spigot 1 the lugs '16 willbe in engagement with the highest points Vof thecams 17, so that the gasket 15 'will be' in intimatey contact with the nozzle 2. Y Thus, during operation, the joint between the spigotand the tube 9 remains sealed, but, when the'o'perat'orde# sires to use lthespigot independently ofthe tube '9, it is onlynecessary for him to swing .v the tube 9 laterally, which action-is accompanied by a movement of the extension downward incident to the engagement `ofthe lugs 16 and movement Vthereof along the camsf17. This downward'movement insures an effective clearance of the gasket v from the formerly engaged edgefof the nozzle 2. Return-movement oflthe ztube 9 causes 'the 'parts tolsnap into 'the seatedv position formerly occupied, and, as shown in Figure 1 of the drawings.-V n

The tube 9 is susceptible-of a substantial range of variation in the details of its vc onstruction 'and includes preferably a horizontal section and an upstanding section, the latter carrying a discharge nozzle 18. The ynozzle the enlarged portion of theI nozzle 18, and is -fixed to a stem or rod ,-21. which depends 'through the upstanding portion of the tube 9 'and extends through thelower wall ofthe tube, the'lower end-portion of thestem 21 carrying a valve 22 designed to be seated on the valve surface 23 formed'in said lower wall. Thus, when the water is turned on through the spigot 1, it Hows as indicatedV by the arrowsin Figure 1, the upstressjof the stream flowing upward through the upstanding portion of tube 9 striking the baffle or disc 20 and elevating the same Vuntil the valve 22 is thereby firmly seatedand Aseals the opening in the llower wallv of tube 9 against leakage; This condition continues as longas the Water flows from the spigot 1V and out through the aperturesv19. s soon as the operator turns olf thespigot 1, the cessa tion in the up stress of the water allows the vdisc 2() to dropiand thereby open Vthe valve 22, so that the water within the tube 9 is al- Vlowed'to flow'freely from the tubea'n'd completelydrain the same. Hence, any particles of saliva., bacteria, or other objectionable matter that might have otherwise been retained'in the fountalinis'drain d out each time thes'pigot is turned o' In Figure lis illustrated a structure similar to that above described,v and suiiciently correspondsthereto to bear the same reference numerals and have the'same description apply, except that the valve seat 23 formed in line with the discharge fronrthe-nozzle 2 of the spigot insteadofvat the outer eXtremadvantage of this change in location -will'become apparent immediately. The tube 9 of the structure seen in Figure 4 is provided with a depending enlargement 9 about the place where the valve se'at23 is provided,`

andacross plate or bracketf24l is arranged within the enlargement v9- and through which bracket extends the stem 21 of the valve 22. `The stem 21 upstands beyond lthe bracket 24C and is provided with'a disc 20jl in theV line of discharge and immediately lbe'- in the tube9 is preferably located at al point Y Y ity of the horizontal portion'of-the tube. The g l neath the lower end ofthe nozzle 2. Apref- Y erablyrelatively Alight spring25 surrounds *they stemv21 between the'disc 20 and thebracket 24, and is tensioned lto sustain the disc 20, stem 21, and valve 22 under ordinary non-operatingV conditions, so that the port formed by the valve seat 23 is retained open when the parts are not in operation'. In

operating'the structure seen in Figure 4,'as-

soon as'the water is turned on,the pressure of discharge on top of the disc 20 overcomes the tension of spring 25 and seats the valve 22"'.so1that the tube 9 is thereby sealed,'and

thedischarge through theifont nozzley continues the same as described Withreference to the structure seen 1n Figure 1- 1 However,

when the supply of liquid'is cutoff, as by the closing of the spigot, cessation of pressure on top of disc 20 permits the spring 25 to function and lift the valve 22"' from Yits seat.

Thereupon,the liquid within the tube`9 drains Y out of the tube in substantially the same man-- ner as occurs in the operation of the structure seen in Figure 1.`

It is particularly to be noted that every facility is provided for insuring a sanitary condition by the effective and complete drainage of liquid remaining in the fountain 2 at the time the pressure is cut olf. The apertures 19 and 19 assure a complete back drainage of every particle of moisture, so -that the liquid can escape freely past the'val've seat 23.
